This project will examine the distribution of Corydalis Incisa in unmanaged areas along the Bronx River using DNA barcode. In 2014-2015 a study of C. incisa was conducted on managed land in the New York Botanical Garden using DNA barcode and a seed collection. The results of this survey found 38 different species of which none were identified as C. incisa. The data collected from this proposal will be compared to the results of the survey conducted in 2014-2015.
